An administrator is setting up an MCP server for a database query tool. The server will be hosted on a Windows machine inside the company network. The GitLab Duo agent is cloud-hosted. Which transport method should the administrator choose for the MCP server?

HTTP (Streamable HTTP) with a publicly reachable or VPN-accessible endpoint.

WebSocket, because it is the only transport supported by GitLab Duo.

stdio, because it is the default and simplest transport.

A custom TCP socket, because it provides the lowest latency.

A user reports that the GitLab Duo agent says 'MCP tool not found' when they ask it to use a tool that was working yesterday. The administrator checks the MCP server and it is running. What should the administrator check next?

Whether the user has permission to use MCP tools in their role.

Whether the MCP server is listening on a different port than configured.

Whether the MCP server's URL has changed in GitLab Duo's configuration.

Whether the tool was accidentally disabled in GitLab Duo's MCP tool management settings.

A company wants to allow the GitLab Duo agent to look up employee information from an HR system and also create calendar events in a scheduling tool. Both systems are external. What is the recommended way to enable both capabilities?

Configure two separate MCP servers, one for the HR system and one for the scheduling tool, and register both in GitLab Duo.

Use GitLab Duo's built-in HR and calendar integrations.

Configure a single MCP server that combines both the HR and scheduling APIs.

Ask the agent to use its web browsing capability to access both systems.

An organization has connected an MCP server that exposes three tools: 'create_jira_ticket', 'read_jira_ticket', and 'delete_jira_ticket'. The security team wants the agent to be able to read tickets but not create or delete them during conversations. What should the administrator configure?

Remove the MCP server from GitLab Duo and re-add it with a read-only API token.

Instruct users to only ask the agent to read tickets and never to create or delete them.

Configure the MCP server to expose only the 'read_jira_ticket' tool by editing its source code.

Disable the 'create_jira_ticket' and 'delete_jira_ticket' tools in the MCP server's tool management settings.

A user reports that the GitLab Duo agent cannot use a configured MCP tool. What is a common first step to troubleshoot this issue?

Rebuild the entire GitLab instance from scratch.

Verify that the MCP server is running and reachable from the GitLab instance.

Uninstall and reinstall the external tool that the MCP server connects to.

Check the user's browser cache for outdated JavaScript files.
